Teradata Virtual Storage (VS):

  • Allocates storage
  • Keeps track of where data is stored on the physical media
  • Maintains statistics on the data temperature (frequency of access) and on the grade (performance metric of storage locations)
  • Automatically migrates more frequently accessed data to faster physical storage and less frequently accessed data to slower physical storage
